GEORGE L. RICE, OF CHICAGO, ILLINOIS, ASSIGNOR TO INTERNATIONAL HARVESTER COMPANY, A CORPORATION OF NEW JERSEY.

SPINNING-MACHINE.

Application filed February 24, 1919.

To all whom it may concern Be it known that I, GEORGE L. Rron, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Spinning-Machines, of which the following is a full, clear, and exact specification.

This invention relates to mechanism for making a combined paper and fiber twine.

The object of the present invention is to provide a strong and flexible fiber paper twine in which the paper and fiber are securely interlocked and intertwisted to form a unitary structure which will withstand severe and harsh treatment and still preserve its unitary construction.

In the present embodiment of the invention the object is accomplished by providing mechanism for producing longitudinal creases in the paper, for disposing nontwisted fiber in the creases of the paper, compressing the fiber and paper into close contact with each other, and intertwisting the fiber and paper with the fiber disposed in the creases of the paper.

The construction illustrated in the present application is an improvement upon the structure shown and described in my copending application Serial No. 228,494, filed April 13, 1918. As in the construction in the application referred to, the paper and fiber are positively drawn, and fedpreferably being fed simultaneously by suitable feeding means such as rollers working under pressure. As the paper and fiber are simultaneously fed through the rollers, the paper is creased longitudinally by pressure of the rollers which force the fiber against the paper. After passing through the feeding means the two elements are passed through suitable mechanism, such as a former, wherein the fiber is evenly distributed across the width of the paper, and the paper and fiber are pressed into close contact with each other. Thereafter the paper tube with the fiber inclosed therein is passed through suitable crushing and condensing means and from this mechanism passes to the spinning mechanism.

I have illustrated inv the accompanying drawings certain specific embodiments of my invention, and in these drawings,-

Fig. 7 is a side elevation of a modified construction of my improved former.

The feeding mechanism for the paper ribbon and the sliver 0r non-twisted fiber 1s substantially the same as that shown in my Patent No. 1,217,067, granted Feb. 20, 1917, and consists of a large feeding roller 19 mounted above and adapted to contact -w1th two small feeding rollers 11 and 12, the rollers 11 and 12 being positively driven by suitable gearing mechanism. These rollers may be supported in any suitable way, the roller 10 preferably being journaled in a slidable journal box and having suitable weighting devices for pressing it into c0ntact with the rollers 11 and 12, this construction being clearly shown in my patent above referred to.

The fiber in the form of a sliver is presented to the feeding rollers by the usual gill bars 13 and gill pins 14:, this construction being old and common and therefore not'being illustrated in detail. The ribbon of paper 15 is drawn by the feeding rollers from a suitable source of supply, such as a roll, and before reaching the feeding rollers passes under or over an idler 16.

The paper roll supporting means is fully shown and described in my copending application above referred to, and this construction has therefore not been illustrated in the present application.

The feeding rollers 10, 11 and 12 positively draw the paper and sliver forwardly and feed them to the former 17, which is mounted on the frame in advance of the feeding rollers. In the present instance the former 17 is made in two sections, a stationary section 18 and a movable or hinged section 19. The section 19 is provided with two upwardly extending lugs 20 which are pivoted on a pin 21 carried by two upwardly extending lugs 22 preferably formed integral with the stationary section 18 of the former. The section 19 has secured thereto or formed integral therewith, an upwardly extending lug 23 by means of which the section may be lifted. Suitable latching means for holding the hinged section in contact with the stationary section is provided, and in the construction illustrated, resilient means is utilized.

The stationary section of the former is provided near its front end with laterally extending lugs 24 and 25, the lug 25 carrying an upright post 26 to the upper end of which is pivoted a bridge plate 27 which is provided at the end opposite its pivot with a laterally extending notch 28. The lug 24 is provided with an upright post 24 having an annular groove 29 adjacent its upper end adapted to receive the notched portion 28 of the bridge plate when the bridge plate is in looking position. The plate 27 has secured thereto or formed integral therewith near its center portion, an upwardly extending barrel 30 inclosing a spring 31 which engages the upper wall 32 of the barrel at one end and a collar at its opposite end. The collar 33 is secured to a plunger 34 which extends through the barrel and is pressed downwardly by means of the spring 31. The plunger is provided at its upper end with a head 35 and at its lower end contacts with a cut-away portion 36 adjacent the front end of the hinged section 19 of the former.

In Figs. 2 and 3 the hinged section of the former is shown in closed position with the plate 27 engaging the upper end of the post 24 and the plunger engaging the cut-away portion 36 of the section 19. hen it is desired to swing the section 19 about its pivot, the lug 3.4 is drawn out of contact with the portion 36 of the section 19 and the bridge plate 27 is swung about its pivot on the post 26 through an angle of approximately 180 to a position directly opposite that shown in Fig. 2. The section 19 may then be lifted.

As illustrated in Figs. 3 and 5 the upper section of the former is convex on its exterior and concave on its interior, the in terior of the section being hollowed out to provide the concave interior surface which engages the paper ribbon.

The stationary section 18 is provided in the present instance with what may be termed a movable bottom 37 which has formed thereon a rear flanged portion 38 adapted to engage the rear edge of the stationary section 18. As shown in the section in Fig. 3, the interiorsurface of the stationary section is beveled or inclined as at 41, and is provided with, a substantially horizontal portion 42. The under-surface of the member 37 also has a corresponding inclined portion 39 and a corresponding horizontal portion 40, these portions of the member 37 being located adjacent the corresponding portions of the stationary sec,- tion 18. The section 18 also has formed therein a substantially vertical cylindrical recess 43 in its horizontal portion 42, and the member 37 is also provided with a corresponding recess 44 located directly above the recess 43. There is seated in these recesses a coiled spring 45 which forces the member 37 upwardly as hereinafter described. The rear upper surface of the member 37 is concave as shown at 40, this concave portion receiving the sliver or nontwiste'd fiber and guiding it to a convex surface 47 which merges with the concave surface and spreads the fibers laterally across the width of the paper ribbon. the ribbon being curved transversely by means of the concave inner surface of the upper section If) of the former. The convex surface 47 of the section 37 is forced upwardly by the spring 45 thereby pressing the strands of the nontwisted fiber into firm contact with the longitudinal creases which have been formed in the paper ribbon. thus insuring the disposition of the strands of the fiber in the creases as the paper and fiber are intertwisted or spun together.

The section 37 has formed therein at its front end a downwardly extending longitudinal rib 48 which is positioned in a correspondingly located longitudinal slot 4.) formed in the section 18 of the former. This rib guides the section 37 in its vertical movement under the influence of the spring 45.

From the above description it will be seen that the movable bottom member 37 may be easily removed or replaced if the occasion should arise, this being done by merely lifting the hinged section of the former and lifting the member 37 from the stationary section. By the provision ol? a spring to press this movable section into contact with the hinged section of the former, the contact of the strands of the fiber with the ribbon of paper is made positive, and the interlocking of these elements is thereby assured.

In Fig. 7 T have illustrated a modification of my construction, substantially the same results being obtained from the use of this form as those obtained by using the colistruction just described. In the modification shown in Fig. 7, the former embodies a stationary section Ill) and a hinged section 51. the stationary section having a concave portion 52 and a convex portion. 53 similar to those abovedescribed. The hinged scction is carried as. in the other instance by a pin 54, but in this instance the upwardly extending lugs 55 formed on the hinged section 51 are provided with diagonal slots 56. the slots being formed approximately on a radius having the point of contact 57 between the front ends of the hinged and stationary sections its center. The locking mechanism for the hinged section has not been illustrated in detail since it is exactly similar to that shown in the other embodi ment. The inner surface of the hinged section is slightly different from that illus trated in connection with the other embodiment since in this embodiment the surface is filled in as shown at 58 to properly coact with the convex portion 53 of the stationary section.

In the modified form just described, and illustrated in Fig. 7, therefore, the upper section 51 is held by means of the spring pressed plunger in engagement with the lower section 52. The upper section, however, is permitted by means of the pin and slot connection 54, 56, to swing about the point 57, thereby pressing the paper ribbon into contact with the fiber strands in a manner similar to that accomplished by the construction shown in Figs. 1 to 6.

It will be clear from the above specification that improved means have been provided for firmly and securely interlocking the separate elements of the fiber paper twine, the construction forming longitudinal creases in the paper and pressing the paper ribbon and the non-twisted fiber in contact with each other as the paper and fiber are being wrapped together and prior to the spinning operation.

While I have in the above specification described two specific embodiments of my invention, I do not intend to be limited in any way to the specific constructions shown and described, but it should be understood that the invention is capable of further modification and that other modifications may be employed without departing from the spirit and scope of the invention as expressed in the following claims:
